•
iT is FORBiDDEN to soften the water according to the principle of ion exchange.
•
Never fill the system with distilled or demineralized water as it will severely corrode the aluminium heat exchanger. Use softened
water for filling and top-ups to reduce the total hardness. Moreover, the water must be conditioned to keep the ph within the
defined range in order to prevent corrosion.
•
Keep a log of the amount of filling and top-up water, of the water quality checks and of the water treatment checks.
•
Install a meter to check the amount of filling and top-up water.
•
The conductivity of the untreated water in the system MUsT NOT exceed 600 µs/cm.
•
In case the system water is treated, please abide by the instructions given by the manufacturer of the product used. Conductivity
MUsT NOT exceed 2000 µs/cm.
•
after replacing the generator, a complete clean up of the system is comPulsoRY.
NOTE: in case the conductivity exceeds the values given above, empty out the system, rinse and fill it with clean and treated cock
water.
